Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a contact lens cleaning / disinfecting apparatus. More particularly, the present invention relates to a contact lens cleaning / disinfecting apparatus for cleaning contact lenses by ultrasonic waves or the like and disinfecting them by boiling disinfection or the like.

[0002]

2. Description of the Related Art In recent years, contact lenses have been widely used in place of eyeglasses, mainly for young women. However, when a contact lens is used, the attached contact lens is contaminated by the attachment of eye oil and proteins in the tears of the eyes, and is contaminated by the attachment of various bacteria (bacteria). For this reason, fogging occurs in the lens, which causes deterioration of eyes.

[0003] Therefore, it is necessary to periodically or irregularly perform cleaning for removing dirt from the contact lens and disinfection for killing various germs. For cleaning contact lenses, the contact lenses are generally immersed in a cleaning solution,
An ultrasonic cleaning method of cleaning by ultrasonic vibration is employed.
For disinfection of contact lenses, a boiling disinfection method has been adopted in which a contact lens from which dirt has been removed in advance or from which dirt has not been removed is immersed in a disinfecting solution and heated and boiled for disinfection. In this case, the removal of dirt before and after disinfection is based on the technique of putting the contact lens on the palm of one hand and rubbing with the fingertip of the other hand using a cleaning agent,
Problems such as a change in power due to deformation and wear of the contact lens and a decrease in transparency due to abrasion have occurred. For this reason, many of today's contact lens users own a cleaning device and a disinfecting device, respectively, and use a method of cleaning and disinfecting them, which is inconvenient in use.

Conventionally, as a measure for solving this inconvenience, cleaning and disinfection can be continuously performed by controlling temperature with one apparatus, for example, as disclosed in Japanese Patent Application Laid-Open No. 5-220205 and US Pat. No. 4,735,223. Some technologies have been proposed.

[0005]

However, both of the above-mentioned techniques are systems in which cleaning is performed in accordance with a program at a preset temperature and time, followed by disinfection. Therefore, cleaning or disinfection cannot be arbitrarily and selectively performed as needed. In the former, a liquid containing a special enzyme is used, and a cleaning effect is obtained by activating the enzyme in a specific temperature range. Therefore, the apparatus is expensive, and the user has a large economic burden.

On the other hand, in the latter, the cleaning effect is obtained by mechanical vibration using a vibrator made of a piezo element at the time of cleaning, and cannot be used at a high temperature (100 ° C. or higher). Therefore, the disinfection of the contact lens is inevitably a sterilization treatment at a low temperature, and a sufficient sterilization effect cannot be obtained.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the prior art, and makes it possible to separately perform cleaning and disinfection as necessary, thereby making the system more convenient to use. Accordingly, it is an object of the present invention to provide a contact lens cleaning / disinfecting apparatus capable of performing sufficient cleaning, and performing boiling disinfection at a high temperature to ensure thorough disinfection.

[0008]

According to the present invention, there is provided a power supply unit comprising a power supply unit having a mounting base, a cleaning unit having a mounting receiver, and a disinfection unit having a mounting receiver. The present invention provides a contact lens cleaning / disinfecting apparatus characterized in that a cleaning unit and a disinfecting unit can be interchangeably mounted on the power supply unit.

According to this structure, the cleaning or disinfection of the contact lens can be arbitrarily and separately performed by mounting the cleaning unit or the disinfecting unit on the power supply unit as required. Therefore, it is convenient for use.

[0010]

In a preferred embodiment, the cleaning unit comprises an ultrasonic cleaning unit for cleaning a contact lens by ultrasonic vibration. Therefore, by cleaning the contact lens with ultrasonic waves, cleaning can be performed without using a specific or special cleaning liquid, and the economical burden on the contact lens user is reduced.

In another preferred embodiment, the disinfecting unit comprises a boiling disinfecting unit for disinfecting a contact lens by boiling. Accordingly, by boiling and disinfecting the contact lens, it is possible to perform boiling and disinfection at a high temperature, so that the contact lens can be thoroughly disinfected.

In another preferred embodiment, the mounting base of the power supply unit and the mounting receiving of the cleaning unit or the disinfecting unit have a concave and convex shape which corresponds and regulates the mounting direction. An operation switch is provided so as to be electrically connected when the cleaning unit or the disinfection unit is correctly mounted on the power supply unit. Therefore, when the cleaning unit or the disinfecting unit is mounted on the mounting base of the power supply unit, a predetermined operation switch is turned ON, and the cleaning unit or the disinfecting unit operates properly and safety is achieved.

Further, in a preferred embodiment,
The mounting table of the power supply unit and the mounting receiver of the cleaning unit or the disinfecting unit have corresponding uneven shapes and are provided with an indication mark for defining the mounting direction on the outer surface of the mounting unit. An operation switch is provided so as to be electrically connected when correctly mounted on the supply unit. Therefore, the cleaning unit or the disinfecting unit can be accurately mounted on the mounting base of the power supply unit, and only when the cleaning unit or the disinfecting unit is correctly mounted, the operation switch is turned ON, and the cleaning unit or the disinfecting unit operates properly and safety is achieved.
